The fixed mold assembly 2 includes a fixed mold base 21, a punch 22, a first die 23, and a second die 24. The fixed mold base 21 is used to provide a basic support structure for the punch 22, the first die 23, and the second die 24. The movable mold assembly 3 includes a movable mold base 31 and a third die 32. The movable mold base 31 is used to provide a basic support structure for the third die 32. The punch 22, the first die 23, the second die 24, and the third die 32 can be combined to form a mold cavity for injection molding the automotive oil filter seat end cover 1.

[0029] Specifically, the first and second concave molds 23 and 24 are both slidably connected to the fixed mold base 21, and are arranged on opposite sides of the punch 22. The inner wall structures of the first and second concave molds 23 and 24 correspond to the outer surface structures of the oil filter seat end cover 1 to be injection molded, while the outer wall structure of the punch 22 corresponds to the inner surface structure of the oil filter seat end cover 1 to be injection molded. Specifically, in this embodiment, the inner wall of the first concave mold 23 and the outer wall of the punch 22 form a first cavity 27, and the interior of the second concave mold 24 and the outer wall of the punch 22 form a second cavity 28.

[0030] Specifically, the movable mold base 31 and the fixed mold base 21 are detachably connected, and the third die 32 is arranged on the movable mold base 31. When the movable mold base 31 and the fixed mold base 21 are close to each other, the interior of the third die 32 and the outer wall of the punch 22 form a third cavity 29, and then, the mold cavity for injection molding the automobile oil filter seat end cover 1 is obtained through the first cavity 27, the second cavity 28 and the third cavity 2927.

[0031] In order to facilitate the control of the first and second dies 23, 24, the present embodiment further includes a first telescopic member 211 and a second telescopic member 212 on the fixed die base 21, wherein the first telescopic member 211 is connected to the first die 23 and is used to drive the first die 23 to slide on the fixed die base 21, and the second telescopic member 212 is connected to the second die 24 and is used to drive the second die 24 to slide on the fixed die base 21. Before injection molding, the first telescopic member 211 and the second telescopic member 212 respectively control the first and second dies 23, 24 to move closer to each other, and during demolding, the first telescopic member 211 and the second telescopic member 212 respectively control the first and second dies 23, 24 to move away from each other.

[0032] Furthermore, in order to provide injection molding accuracy, this embodiment also provides a plug-in block on the first die 23 or the second die 24, and a plug-in slot on the other. The plug-in block and the plug-in slot work together to position the connection between the first die 23 and the second die 24.

[0033] Reference Figure 4 In this embodiment, a first stopper 33 and a second stopper 34 are provided on the side of the movable die holder 31 facing the fixed die holder 21. The first stopper 33 and the second stopper 34 are arranged oppositely on either side of the third die 32. When the first and second dies 23 and 24 are attached to each other, the first stopper 33 is positioned on the red side of the first die 23 away from the second die 24 and is attached to the first die 23. The second stopper 34 is positioned on the side of the second die 24 away from the first die 23 and is attached to the second die 24.

[0034] Furthermore, the first limit block 33 is provided with a first limit surface 331 facing the second limit block 34, and the second limit block 34 is provided with a second limit surface 341 facing the first limit block 33. The first limit surface 331 and the second limit surface 341 gradually move away from each other in the direction from the movable mold base 31 to the fixed mold base 21. In this embodiment, the angle between the extension line of the first limit surface 331 and the second limit surface 341 can be set to 40°.

[0035] Correspondingly, abutment surfaces 25 are provided on the side of the first die 23 away from the second die 24, and on the side of the second die 24 away from the first die 23. The inclination of the abutment surface 25 is the same as that of the first limiting surface 331 or the second limiting surface 341. Therefore, when the movable die base 31 moves downward until it is in contact with the fixed die base 21, the first limiting surface 331 and its corresponding abutment surface 25 are in contact, and the second limiting surface 341 and its corresponding abutment surface 25 are in contact. Under the action of the first limiting block 33 and the second limiting block 34, the first die 23 and the second die 24 will remain in contact, thereby improving the injection molding quality.

[0036] Furthermore, a clamping block 35 is provided on the side of the first limit block 33 and the second limit block 34 facing the fixed mold base 21, and a clamping groove 26 is provided at the corresponding position of the abutting surface 25 of the first concave mold 23 and the second concave mold 24. When the movable mold base 31 moves downward until it is in contact with the fixed mold base 21, the clamping block 35 is clamped into the clamping groove 26, further ensuring the stability of the injection molding.
